{"version":"1.0","type":"rich","title":"Points on a Map","description":"This visualization displays a world map with circles positioned at the coordinates of cities. The size of each circle is proportional to the city's population, using a square root scale to visually encode the data. Built with React and D3 version 5, the map uses the `geoNaturalEarth1` projection and `geoPath` to render land, graticules, and country interiors from World Atlas TopoJSON. City data is loaded from a CSV file, and the visualization is rendered as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c857901d2d0445d8a1e2ec74fdb3770f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
